Financial prediction is complex due to the stochastic nature of the stock market. Semi-structured financial documents present comprehensive financial data in tabular formats, such as earnings, profit-loss statements, and balance sheets, and can often contain rich technical analysis along with a textual discussion of corporate history, and management analysis, compliance, and risks. Existing research focuses on the textual and audio modalities of financial disclosures from company conference calls to forecast stock volatility and price movement, but ignores the rich tabular data available in financial reports. Moreover, the economic realm is still plagued with a severe under-representation of various communities spanning diverse demographics, gender, and native speakers. In this work, we show that combining tabular data from financial semi-structured documents with text transcripts and audio recordings not only improves stock volatility and price movement prediction by 5-12% but also reduces gender bias caused due to audio-based neural networks by over 30%.

Data to Value: An 'Evaluation-First' Methodology for Natural Language Projects

While for data mining projects (for example in the context of e-commerce) some methodologies have already been developed (e.g. CRISP-DM, SEMMA, KDD), these do not account for (1) early evaluation in order to de-risk a project (2) dealing with text corpora (“unstructured” data) and associated natural language processing processes, and (3) non-technical considerations (e.g. legal, ethical, project management aspects). To address these three shortcomings, a new methodology, called “Data to Value”, is introduced, which is guided by a detailed catalog of questions in order to avoid a disconnect of large-scale NLP project teams with the topic when facing rather abstract box-and-arrow diagrams commonly associated with methodologies.

Despite recent advances in deep learning-based language modelling, many natural language processing (NLP) tasks in the financial domain remain challenging due to the paucity of appropriately labelled data. Other issues that can limit task performance are differences in word distribution between the general corpora – typically used to pre-train language models – and financial corpora, which often exhibit specialized language and symbology. Here, we investigate two approaches that can help to mitigate these issues. Firstly, we experiment with further language model pre-training using large amounts of in-domain data from business and financial news. We then apply augmentation approaches to increase the size of our data-set for model fine-tuning. We report our findings on an Environmental, Social and Governance (ESG) controversies data-set and demonstrate that both approaches are beneficial to accuracy in classification tasks.

In this half-day tutorial, we will review the basic concepts of, methods for, and applications of geographic information retrieval, also showing some possible applications in fields such as the digital humanities. The tutorial is organized in four parts. First we introduce some basic ideas about geography, and demonstrate why text is a powerful way of exploring relevant questions. We then introduce a basic end-to-end pipeline discussing geographic information in documents, spatial and multi-dimensional indexing [19], and spatial retrieval and spatial filtering. After showing a range of possible applications, we conclude with suggestions for future work in the area.

Zum Treuhänder des Sicherungsvermögens unter dem neuen Versicherungsaufsichtsgesetz – Auswirkungen der Solvency II-Umsetzung

In dem Beitrag werden die Auswirkungen der Umsetzung der Solvency II-Richtlinie in das neue deutsche Versicherungsaufsichtsgesetz (VAG 2016) auf den Treuhänder des Sicherungsvermögens untersucht. Der Treuhänder des Sicherungsvermögens gehört zu den nationalen Sicherungsmechanismen, um Versicherungsnehmer für den Fall der Insolvenz ihres Versicherungsunternehmens zu schützen. Für Solvency II-Versicherungsunternehmen entfiel die bisherige deutsche Anlageverordnung (AnlV) zum 01.01.2016. Statt eines vorgegebenen Anlagekatalogs sind die Versicherungsunternehmen nun verpflichtet, eine interne Anlagerichtlinie zu haben, die auch Grundlage der Überwachung des Sicherungsvermögens durch den Treuhänder ist. Herausforderungen ergeben sich aus der Kollision der Rechnungslegungssicht (HGB) mit der Solvency II-Marktwertsicht. Die Untersuchung leistet damit einen Beitrag zum besseren Verständnis des Zusammenspiels zwischen unveränderten rechtlichen Normen und der neuen ökonomischen, risikobasierten Solvency II-Perspektive.
